RegulationofSpermatogenesisbyCREM
The transcriptional regulator CREM plays a key role in spermatogenesis, acting as a central transcription factor triggering a cascade of transcriptional activation of post-meiotic genes involved in this process such as calspermin and testis angiotensin-converting enzyme. The key role of CREM in sperm formation is demonstrated by the male sterility of mice lacking CREM, the failure of spermatids to develop into mature......阅读全文
